Description

Description: FIELD OF THE INVENTION The present invention relates to a kitchen waste disposal apparatus for heating and incinerating kitchen waste generated at home.

2. Description of the Related Art Generally, there is a kitchen waste treatment apparatus by methods such as heating and combustion by gas, compression crushing and fermentation decomposition, but all of them have problems in noise, foul odor, weight loss, etc.
It was unsuitable for use in the home kitchen.

Therefore, the inventors of the present invention have considered a garbage treatment device using a furnace and a heater as shown in FIG. That is, the frame body 101 is a box body having an upper surface opened and provided with a lid 104, and a heat-resistant furnace material 102 is stuck all over the inside thereof. A heater 103 is provided at the bottom of the frame 101, and an air inlet 107 from an air blower 108 is provided on the inner wall, and an exhaust port communicating with the outside through a purifier 110.
109 is provided. Processing container 105 on the heater 103
Place and put kitchen waste 106 in this. And heater 103
When the electricity is turned on, the kitchen waste 106 is heated and dehydrated, and then ignited and incinerated for weight reduction. At this time, the air required for combustion is the air supply port
The exhaust gas introduced by the blower 108 through 107 enters into the purifier 110 through the exhaust port 109, is heated by the exhaust gas heating heater 111, is purified by passing through the catalyst 112, and is then exhausted. It was

Problems to be Solved by the Invention In such a conventional configuration, when oil or synthetic resin enters during combustion in the frame 101, a large amount of soot occurs,
The catalyst eyes in the purifier were sometimes clogged with soot. Further, for this reason, there is a problem that exhaust gas fills the inside of the frame 101, causing an explosion or the like.

The present invention solves the above-mentioned problems, and an object of the present invention is to provide a safe garbage disposal device that prevents damage to equipment by preventing soot clogging in the purifier.

Means for Solving the Problems In order to solve this problem, the present invention has a box-shaped frame body having a lid that can be opened and closed, and a heat-resistant furnace material attached to the inside of the box-shaped frame body.
While providing an air supply port and an exhaust port on the inner surface of the frame,
A heater projecting inward is fixed to the bottom surface, and a garbage processing container having a recessed portion on the bottom surface that covers the heater and the exhaust port are provided with a purifier that communicates with each other to purify the exhaust gas. Inside, a catalyst and an exhaust gas heating heater provided below the catalyst, and a pipe for blowing air to the bottom of the catalyst are provided, and an air pressure feeding device that communicates with the pipe and sends air is provided. It was done.

Function With this configuration, soot generated in large quantities due to the processing of oil and synthetic resin is blown off from the pneumatic pump along the lower part of the catalyst by the pipe, soot is blown off and the clogging of the catalyst is prevented, and it is reburned. Becomes

Embodiment An embodiment of the present invention will be described below with reference to FIG. In the figure, reference numeral 1 denotes a frame, which constitutes a box made of a material having high heat resistance such as metal or ceramic, and the inside thereof has a furnace material made of a material such as ceramic fiber having a higher heat resistance and a heat insulating effect. Is lined. A heater 3 for heating the kitchen waste 6 that penetrates the furnace material 2 from the outside and projects into the frame 1 is provided on the inner bottom of the frame 1. The top of the frame 1 is a lid 4 that can be opened and closed so that kitchen waste 6 can be inserted.
Is provided. In addition, a processing container 5 for kitchen waste 6 formed on the upper portion of the heater 3 and a protrusion that encloses the heater 3 on the bottom.
Is provided, and the kitchen waste 6 introduced by opening the lid 4 is stored in the processing container 5. Further, an air supply port 7 is opened on the side wall of the frame body 1 so that air necessary for combustion of the kitchen waste 6 flows into the blower 8, and the gas generated by the combustion is opened on the side wall of the frame body 1. Exhaust port 9
The gas is discharged from the fuel cell, communicated with it, introduced into the purifier 10, heated by the exhaust gas heating heater 11, purified through the catalyst 12, and discharged to the outside. Further, a pipe 13 for sending air is provided below the catalyst 12, and the air is blown along the lower part of the catalyst 12 by an air pressure feeding device 14. The nozzle portion at the tip of the pipe 13 is thin and flat horizontally.

In the above configuration, the kitchen waste 6 has the lid 4 opened and the processing container 5
It is thrown in. Then, when the heater 3 is energized, the kitchen waste 6 is heated and dehydrated, and then ignited to reduce the amount by incineration. At this time, the air required for combustion enters into the frame 1 from the air supply port 7 opened in the frame 1 by the blower 8, and the exhaust gas emits the exhaust gas into the frame 1.
The gas is introduced into the purifier 10 communicating with the exhaust port 9 opened at, is heated by the exhaust gas heating heater 11, is purified by the catalyst 12, and is then discharged. At this time, a large amount of soot is generated when the oil or synthetic resin is treated, and the catalyst 12
To prevent soot from adhering to the lower part of the and clogging the eyes, blow air from the air pressure feeding device 14 along the lower part of the catalyst 12 from the pipe 13, blow out the soot, and promote the reburning of the soot. As a result, soot does not adhere to the catalyst 12 and clogging is prevented.

EFFECTS OF THE INVENTION As described above, according to the present invention, a large amount of soot is generated when oil or synthetic resin is treated, and blows off the soot that tends to adhere to the lower part of the catalyst in the purifier, and reburns. Therefore, it is possible to prevent inability to supply air due to the soot of the catalyst, thereby preventing abnormal combustion and explosion in the frame, and thus it is possible to obtain a safe device. It is a thing.
